摘要
在参比电极体系有无鲁金毛细管的条件下 ,测定了 316不锈钢在不同浓度NaCl溶液中的电化学阻抗谱 .
The extraneous high-frequency phase shifts in EIS can obscure experimental data and cloud the true analysis of a spectrum. So it is very important to discern the artifacts resulted from various factors during experiment and analysis. The EISs of 316 stainless steel in NaCl solutions of different concentrations were measured with and without Luggin capillary. The results showed that the large internal resistance of the reference electrode system induced capacitive high-frequency phase shift in impedance measurement. It was also observed that high-frequency phase shifts were reduced with the decrease of solution resistance and the internal resistance of reference electrode system.
